UGC NET CSE | October 2020 | Part 2 | Question: 34

Question

The period of a signal is $100$ ms, then the frequency of this signal in kilohertz is ______

• A. $10$
• B. $10^{-1}$
• C. $10^{-2}$
• D. $10^{-3}$

Answer 1

Frequency (in HZ)  =1/Time period (in sec)

here  time =100 ms =100x10^-3 =0.1 sec

so Frequency (in HZ)  = 1/0.1=10 Hz

frequency of this signal in kilohertz is 10/1000=10^-2  

option C
